Ooops. Word on the digital street is Amazon released a listing for Star Wars Battlefront 3 that gave out choice information on the LucasArts Action game. The pages specified PlayStation 2, PlayStation 3, Xbox 360, Wii, Nintendo DS and PSP versions of the game, with a March 2009 release date. They quickly pulled the listing.
Right now, the developer of the game (if it exists!) hasn't been revealed, but it's probably not Pandemic, who developed the first two titles. Likely candidates include Rebellion or Free Radical.
Time, as they say, will tell. Perhaps all will be clear at next week's E3 convention!
